Policy and private sector
Indian Space Policy 2023
Copy link to Indian Space Policy 2023Prelims and Mains
The policy settled the division of labour in 2023, so the argument since has been about pace rather than direction. It also set the terms of the opening: what data is free, how much foreign money may come in, and what ISRO stops making.
- The frontier missions ISRO keeps for itself include Gaganyaan, Chandrayaan-4, the Bharatiya Antariksh Station by 2035 and a crewed Moon landing by 2040.
- Earth observation data coarser than 5 m is made available free, while finer data is not.
- Foreign direct investment is allowed to 74 per cent by the automatic route for satellites, 49 per cent for launch vehicles and spaceports, and 100 per cent for components.
- About 450 space startups are registered, against a handful in 2020.
- India's space economy is about $8.4 billion, under 2 per cent of the world's, against a target of $44 billion by 2033.
ISRO
- Research and new technologies
- Share technology with industry
- Human spaceflight roadmap
- Move out of manufacturing operational systems
IN-SPACe
- Authorise launches, satellites, ground stations
- Promote and hand hold industry
- Open access to government facilities
NSIL
- Commercialise publicly developed technology
- Commercial launches for Indian and foreign clients
Non-governmental entities
- End to end space activities
- Build and operate satellites and ground assets

- ISRO's employee associations asked whether the agency would stop building launch vehicles and routine satellites; the answer given was that the shift is ecosystem expansion and not privatisation.
- The staff cite vacant posts, scientists leaving and revenue given up on commercial launches.
- Almost 80 per cent of ISRO's budget already goes to industry.
16 Aug 2026
- A kilogram to low earth orbit cost $13,302 on Indian rockets in 2025, the highest among major nations.
- The global average was $3,868 and the United States $3,225.
- The cause is rarity rather than inefficiency: India flew five launches that year, mostly on small rockets.
16 Jul 2026Update
- After about 100 personnel quit across centres, against a sanctioned strength of 18,142 with 2,613 posts vacant, the Department of Space directed that resignations and voluntary retirement of scientific staff linked to Gaganyaan and other critical projects not be accepted as routine until those projects are complete.

IN-SPACe

Every private space activity in India ends at the same desk, and IN-SPACe both authorises it and promotes it. The second job is the one that matters to a startup, because it opens government test and launch facilities to firms that could never build their own.
- It has issued 113 authorisations to 52 non-governmental entities.
- It has invited private operators to run the small satellite launch complex at Kulasekarapattinam, Tamil Nadu.
- A private operator at a launch complex raises questions of safety, liability and accountability to Parliament.

- Under the invitation to run the Kulasekarapattinam launch complex, the private operator would handle launch campaigns and safety, with ISRO guiding for one year or three campaigns, whichever comes first.

Space debris and re-entry
How an object leaves orbit
Copy link to How an object leaves orbitPrelims and Mains
- Planned re-entry
- Bringing a spacecraft or rocket stage back into the atmosphere deliberately, at a chosen time and over a chosen place, rather than letting it fall where it will.
An orbit is not a parking space: the atmosphere reaches faintly into the lowest of them and drags whatever is there slowly down. How long that takes, and what survives the fall, is what the re-entry rules are written around.
- Atmospheric drag pulls a low orbit down on its own, so an object in low earth orbit comes back in years or decades whether anyone means it to or not.
- Higher orbits have too little air for drag to do that work, so an object left there stays.
- Re-entry does not destroy everything: light structure burns up, while dense parts such as tanks and engine components can survive to the ground.
- That is why a planned re-entry is aimed at open ocean, and why where a dead object comes down is no longer its owner's business alone.

India's re-entry rules
Copy link to India's re-entry rulesPrelims and Mains
IN-SPACe issued India's first guidelines on planned re-entry on the third National Space Day. They settle a question of jurisdiction as much as one of safety, since a falling object does not consult the map beneath it.
- Any Indian entity carrying out a planned re-entry, anywhere, needs IN-SPACe authorisation.
- A foreign entity re-entering over Indian territory must work through an Indian incorporated entity answerable to Indian law.
- They draw on the United Nations Guidelines for the Long-term Sustainability of Outer Space Activities.

30 Jul 2026Update
- IN-SPACe issued guidelines for the planned re-entry of space objects. Only objects designed to survive re-entry, or planned for it, need authorisation.
- Also in news: NASA launched a robotic mission to catch and tow the falling Neil Gehrels Swift Observatory to a stable orbit, a test of servicing satellites in orbit.

- Artemis Accords
- A United States led, non-binding set of principles for the peaceful and transparent exploration and use of the Moon and other celestial bodies, including rules on resource extraction.
- Moon Agreement
- The 1979 United Nations treaty declaring the Moon and its resources the common heritage of mankind. Few spacefaring nations have ratified it.
- Space debris
- Dead satellites, spent rocket stages and fragments from break ups and collisions, left in orbit at orbital speed, so that even a small piece can destroy a working spacecraft.
- Active debris removal
- Deliberately capturing a dead object and taking it out of orbit, rather than waiting on atmospheric drag.
- Technology transfer
- Handing a mature design and its manufacturing expertise to industry, with the developer supporting the company for a fixed period.
- Earth observation constellation
- A group of imaging satellites flown and operated together, so that a place on the ground is photographed far more often than a single satellite could manage.
- hyperspectral
- Imaging in hundreds of narrow wavelength bands rather than a few broad ones, which lets a satellite tell materials apart instead of only seeing shapes.
